Importancia del rabdomioma cardiaco en población pediátrica. Experiencia de 39 años. Serie de casos

INTRODUCTION: Rhabdomyomas are the most prevalent benign heart tumors in the fetal stage and during childhood. OBJECTIVE: Our objective is to make known our experience over 39 years in pediatric patients with rhabdomyoma in our institution, as well as to emphasize the importance of its detection, study and control due to the association it has with tuberous sclerosis (TS). MATERIAL AND METHODS: We conducted a retrospective, descriptive and cross-sectional study, from January 1980 to March 2018. Twenty-four met our criteria, we collected information regarding the clinic and cabinet studies, as well as their evolution and the treatment given. They were called by telephone to know their evolution and current status. RESULTS: We found 51 patients with a diagnosis of cardiac tumor, of which 24 were rhabdomyomas. The diagnosis was made prenatal in 8 patients, 5 at birth and in 11 during the first year of life. The most frequent clinical manifestations were the presence of murmur, arrhythmias, cyanosis, dyspnea, and diaphoresis. In 17 of them a diagnosis of TS was made. Half had follow-up by neurology, 10 by dermatology, 8 by ophthalmology and 4 with genetics. Half were left under surveillance, 7 were given medical treatment and 5 required surgery. Regarding the clinical evolution 17 patients remained stable, 5 presented spontaneous regression and 2 died. CONCLUSIONS: Rhabdomyoma is a rare benign tumor, its evolution can be malignant and associated with TS, it darkens the prognosis.
